I am getting 182 I/O status errors (invalid variable name), reading namelists that have variables with underscores and numeric characters in them. Is this normal? I have not found anything in the release notes or the users guide about special naming conventions for namelist variables. The variables that are causing problems all have an underscore and a number at the end of the name, (e.g. "REFINE_MAN_1"), which is the only thing I can see that differentiates them from other variables in out namelists. We have variables with underscores that read fine, and we have variables with numbers at the end of the name that read fine. If I exclude the variables named in this way the namelist read succeeds with no errors.
We are using Version 7.0 (Build 20021028Z) on RH7.2.
